Fun anecdotes in there a-plenty, but also a pretty good assessment of what the modern bench coach is really all about:

Bench coaches have more responsibilities than ever. With managers diverted to pregame and postgame news conferences and other demands, they must delegate more. “Bench coaches run spring training and do things like schedule batting practice and stretching before games,” Pettini said.

Baseball’s technological and numbers revolution has also expanded the bench coach’s portfolio to include monitoring scouting reports and statistics.

Being a manager is like having any other high-responsibility, high-pressure job. You gotta have an assistant who can make sure you have the stuff you need when you need it and who, when you’re occupied with something else, can think about the things you’re missing.

I’d still want one that would drink beers with me after the game, of course. Just as long as he could also do that other stuff too.

Basic concepts of irony and self deprecating humor are clearly lost on you, but… hey… it’s a baseball blog, no big deal.
What concerns me is your view of “credibility”. You get to vote. There really needs to be some IQ test for both candidates and voters.
